Just read section 36 and noticed you have some data for 5w-20 Renewable Lubricants Bio-Syn. Have you fully tested it yet? I know you tested the 5w-30 I sent you, and I am now running it in my Lexus V-8s because they have terrible fuel dilution issues from the OEM tune (rich is safer than lean, so let the catalysts clean it up so we don’t have to replace engines under warranty because someone put bad fuel in this thing and our tune was too tight). Actually, to the point I bought a 5 gallon bucket – these Lexus engines need almost 10 quarts for an oil change(!?!) and I remember as a youngster my dad talking about the importance of the 10 quart capacity in the 302 Chevrolets he built for dirt track racing. Anyway, from what I read in your new article, the oil from Renewable Lubricants seems to be at or very near the top of the game for load capacity under a wide range of conditions. Sad to see their sales and marketing isn’t as good as their tribology.
Which brings me to a real question – a number of top performing oils do not carry an API rating of any kind. Any thoughts on why a company would choose this path, knowing full well that many people will default to a rated oil to ensure their manufacturer’s warranty remains intact? I don’t know enough about the industry to understand why they wouldn’t choose to get their oil rated when they’ve put so much effort into making a quality product.

Hi again,
For Tech Article 36 on motor oil Viscosity Index, I referenced manufacturer specs for the cSt and VI values for comparison.
I have not tested the wear protection capability of 5W20 Renewable Lubricants Bio-Syn.
Something for everyone reading this to clearly understand, you do not just pour extra oil into an engine and declare that it has more oil capacity. Doing that could destroy an engine, because of all the extra oil churning and windage, that will turn the oil into air-filled foamy oil. An engine needs “LIQUID” oil for proper lubrication and protection, NOT air-filled foamy oil. In order to properly increase an engine’s oil capacity, the sump capacity must be increased. Hopefully you have done it the correct way.
I increased the sump capacity on my own 800 HP, 540 cubic inch (8.9L) Big Block Chevy engine, from 5 qts to 9 qts, when I built it.
I can tell you precisely why smaller Oil Companies often do not have API certifications on their oils. Their oil may not be formulated properly to meet all the certification requirements. But most often, the reason comes down to one word – COST. I have spoken with a couple of Oil Company Chemical Engineers, over the years about that. And they told me the COST of going through the API certification process, is prohibitively expensive for smaller Oil Companies to afford. So, there you have it.
I received your shipment with the different version of Bio-Syn oil. I should get a chance to test it, sometime in the coming weeks. And I will post the results here in my Blog when I have them.
